The age of "the oldest pot plant in the world" - a cycad of the species Encephalartos altensteinii which can be found at Kew Botanical Garden's in London.
It was collected in South Africa in 1773 and brought to Kew in 1775 where it now grows in the Palm House.
The Eastern Cape giant cycad, as it is known, has been used as a food source in its native range by removing the stem pith, burying it, rotting it, digging it up, kneading and baking it.

There will be lots more photos from Kew in the next post.
